Answer
Most base coats mix 50-50, sherwin williams and dupont require a special reducer for the base coat, some others can use standard urethane reducer.most clears mix 4 parts clear to 1 part reducer and 1 part activator. some clears use no reducer, and some mix different ratios. use a glass or plastic one quart kitchen measuring cup to mix in & get the right ratio.
